Prior studies on e-learning service quality were conducted mainly in developed countries; however, little effort has been made in emerging countries. This study examines the relationships among e-learning service quality attributes, overall elearning service quality, e-learning student satisfaction, and e-learning student loyalty in the context of Vietnam, an emerging country. Survey data collected from 1232 college students were analyzed by means of exploratory factor analysis, confirmatory factor analysis, and structural equation modeling using SPSS 25 and SmartPLS 3.0. The results indicated that e-learning service quality was a second-order construct comprising of three factors, namely, e-learning system quality, e-learning instructor and course materials quality, and e-learning administrative and support service quality. The e-learning system quality was the most important dimension of overall e-learning service quality, followed by e-learning instructor and course materials quality, and e-learning administrative and support service quality. In addition, the overall e-learning service quality was positively related to e-learning student satisfaction, which in turn positively influences e-learning student loyalty. Also, overall e-learning service quality has a direct effect on e-learning student loyalty. Implications for colleges and universities are discussed.

Purpose -The purpose of this study is to examine the effects of consumers' perception of online retailers' ethical behavior on consumer purchase and revisit intentions. Design/methodology/approach -A sample of 259 online shoppers was employed to test the relationships between perceived ethics of online retailers and the intention to revisit and purchase. The measurement model and structural relationships were estimated using AMOS 18. Findings -Results show that perceived ethics of an Internet retailer's website significantly affect consumers' trust and attitudes to the retailer's website that eventually have positive impacts on purchase and revisit intentions. Website trust was positively related to attitude toward the site. The results do not show support for a direct effect between perceived ethics and behavioral intentions, but attitude and trust toward the website mediate these effects. Practical implications -The findings support the idea that despite the physical distance between online retailers and customer, behaving ethically has an effect on revisit and purchase intentions. This suggests that online vendors should invest in methods that strengthen consumers' trust of websites. To convey a sense of ethics of the website, websites should ensure that privacy policies are easy to understand, explain clearly how customer information is used, offer secure payment methods, display clearly the terms and conditions of the online transactions, fulfill the orders, and avoid deceptive practices and exaggerations of product characteristics. Originality/value -Research integrating perceived ethical conduct of retailers and consumer behavior is still in the beginning, and has not explored all outcomes of perceived ethics. This study is an initial attempt to investigate the effects of perceived ethics of retailers on revisit and purchase intentions. This study contributes to the knowledge of consumer perceived ethics and behavioral intentions.

Purpose-This paper aims to examine the effects of consumers' perceptions concerning the ethics of online retailers on web site satisfaction and loyalty. Design/methodology/approach-An online survey instrument was administered to a sample of 220 students who were enrolled in various business undergraduate classes at a mid size university located in the southwestern USA. Participants completed a questionnaire based on their latest online purchase. The measurement model and structural relationships were estimated using AMOS 18. Findings-Non-deception, fulfillment, and security are significant predictors of web site satisfaction. Only privacy is related directly with loyalty. While direct effects of fulfillment and non-deception on loyalty are not significant; satisfaction mediates these relationships. Results provide a strong support for the web site satisfaction-loyalty relationship. Practical implications-Internet retailers must address ethical issues surrounding their web sites by protecting financial and personal information, delivering accurate products, and avoiding deceptive practices. Originality/value-The current research is one of few studies in online retailing that examines the relationship between perceived online ethics, satisfaction and loyalty. By offering evidence to prior conflicting results in the literature, a strong association between what consumers perceive as ethical online retailing, their satisfaction and loyalty to online retailers was confirmed.

This study systematically analyzes the research that used the Health Belief Model (HBM) as a theoretical basis to examine the influence of HBM constructs on COVID-19 vaccine hesitancy. Following PRISMA guidelines, PubMed, Web of Science, Google Scholar, and Scopus were searched for quantitative studies. Sixteen studies with 30,242 participants met inclusion criteria. The prevalence of COVID-19 vaccine hesitancy was 33.23% (95% CI 24.71–41.39%). Perceived barriers and perceived benefits were the most common HBM constructs that were significantly associated with vaccine hesitancy. While perceived benefits was inversely associated, a positive association was found between perceived barriers and vaccine hesitancy. Other HBM constructs that were frequently examined and inversely associated were perceived susceptibility, cues to action, perceived severity, and self-efficacy. The most common HBM modifying factor that was directly associated with COVID-19 vaccine hesitancy was gender, followed by education, age, geographical locations, occupation, income, employment, marital status, race, and ethnicity; however, a few studies report inconsistent results. Other modifying variables that influenced vaccine hesitancy were knowledge of COVID-19, prior diagnosis of COVID-19, history of flu vaccination, religion, nationality, and political affiliation. The results show that HBM is useful in predicting COVID-19 vaccine hesitancy.

Purpose Previous studies that examined the role of empathy and nonverbal immediacy on business-to-business (B2B) salesperson performance is limited in scope and yielded inconclusive evidence. Grounded in Plank and Greene’s (1996) framework of salesperson effectiveness, this paper aims to empirically investigate the mediating role of adaptive selling behavior through which empathy and nonverbal immediacy influence sales force performance and the form of empathy (cognitive or affective) that has the most beneficial role in improving relationship (versus outcome) salesperson performance. Design/methodology/approach Using cross-sectional data that were collected from 422 pharmaceutical sales representatives, this study used structural equation modeling to test the hypothesized relationships. Findings Adaptive selling behavior mediates the effect of perspective taking empathy and empathic concern on relationship performance. However, the impact of empathy on outcome performance is not significant through adaptive selling behavior, but perspective taking empathy has a direct influence on outcome performance. Contrary to expectations, nonverbal immediacy is not mediated by adaptive selling behavior but has a direct and positive impact on relationship performance. Research limitations/implications The results of this study have several implications for recruitment, training and assessment of salespeople in a B2B context. Based on the empirical evidence, it is highlighted that firms may use different forms of empathy and nonverbal cues to promote adaptive selling behavior that impact sales force performance (i.e. outcome or relationship). Originality/value To the authors’ knowledge, this is the first study which simultaneously examines the mediating role of adaptive selling behavior in the relationship between three antecedent variables that relate to sales force empathy and nonverbal communication (i.e. perspective taking empathy, empathic concern and nonverbal immediacy) and two aspects of B2B sales performance (relationship and outcome).

Purpose By testing a moderated mediation model, the purpose of this paper is to examine the mediating role of credit card self-efficacy in the relationship between credit card literacy and financial well-being. The authors further examine if credit card number moderates this effect. Design/methodology/approach Data for the study were collected from 427 college students. The PROCESS macros in IBM SPSS Statistics 23 was used to assess the hypothesized relationships. Findings Credit card literacy positively influences financial well-being through self-efficacy. However, this effect is stronger when college students own fewer credit cards. Practical implications Banks and credit card issuers, policymakers and colleges and universities should place a greater emphasis on credit card literacy programs that enhance students’ general understanding of credit card terms and conditions and confidence in their ability to effectively use and manage their credit cards. Originality/value To our knowledge, this is the first study to examine the relationship between credit card literacy, self-efficacy and financial well-being.
